I always wondered how that 34 year old Chinese doctor died of the disease and why healthcare workers were at greater risk of poor outcomes. Maybe this is common knowledge but I had no idea the amount of virus you were exposed to affected the severity of your symptoms. I thought it was your immune system that determined how sick you got and how quickly you recovered from an illness.Quote:
Virus experts know that viral dose affects illness severity. In the lab, mice receiving a low dose of virus clear it and recover, while the same virus at a higher dose kills them. Dose sensitivity has been observed for every common acute viral infection that has been studied in lab animals, including coronaviruses.

At the same time, we need to avoid a panicked overreaction to low-dose exposures. Clothing and food packaging that have been exposed to someone with the virus seem to present a low risk. Healthy people who are together in the grocery store or workplace experience a tolerable risk so long as they take precautions like wearing surgical masks and spacing themselves out.
A complete lockdown of society is the most effective way to stop spread of the virus, but it is costly both economically and psychologically. When society eventually reopens, risk-reduction measures like maintaining personal space and practicing proper hand-washing will be essential to reducing high-dose infections. High-risk sites for high-dose exposure, like stadiums and convention venues, should remain shuttered. Risky but essential services like public transportation should be allowed to operate but people must follow safety measures such as wearing masks, maintaining physical spacing and never commuting with a fever.

Reveille on the main update thread sounded skeptical about the prospects of Aggie football this fall. This sheds light on why this will be difficult without a vaccine or herd immunity in place. Sitting shoulder to shoulder with an infectious person for 4 hours would be no bueno.
